Robert has just seven hours to feed 90 cast and crew from the series LOST, and just like the characters in the show he'll have to 'make do' - before he can even begin to cook, he must build his kitchen.
Robert caters a dinner for 500 at the Philadelphia Zoo, where every dish must be based on the diets of the zoo's four most popular animals: big cats, primates, birds and reptiles.
